mcp_census_server

Authentication

All requests to the MCP Census Server must include a valid API key in the X-API-Key header.

X-API-Key: <SERVER_API_KEY>

• If the header is missing or incorrect, the server returns 401 Unauthorized.
• If the server is misconfigured (no key set), requests return 500 Server configuration error.

Use this header on every JSON-RPC call (initialize, tools/list, tools/call).

Environment Setup

Environment variables can be defined in a .env file at the project root. Copy the included example and fill in your keys:

cp .env.example .env

Then edit .env:

CENSUS_API_KEY=your_census_api_key_here
SERVER_API_KEY=your_server_api_key_here
# Optional: LOG_LEVEL=INFO
